STREET-LAM P.

SPECIFICATION forming part of Letters Patent No. 286,763, dated October16, 1883.

To all w/eom it may concern.-

Be it known that I, HENRY S. BELDEN, a citizen of the United States,residing at Canton, in the county of Stark and State of Ohio, haveinvented certain new and useful Improvements in Street-Lamps, of whichthe following is a specification, reference being had therein to theaccompanying drawings.

, Figure 1 is 'a View of my improved apparatus, shown attached to anordinary streetlamp. Fig. 2 is avertieal section of the stopcock. 7 Arepresents the body of an ordinary streetlamp, provided with a verticalor somewhat sloping wall or walls, A.

Bis a reservoir attached in any of the usual ways to the lamp.

0 represents the burner, connected with the reservoir by means of thefeed-pipe D.

This pipe 1) is connected to the atomizer I by means of elbow-joint E,which is provided with screw-threaded sockets c c for their reception.

e is a small supplemental tube attached to the rear side of theelbow-joint E. It is internally screw-threaded, and extends through thewall A of the lamp, to provide a bearing for the valve-screw F. The heador handle F of said valve-screw is outsideof the lantern, and permits aready manipulation of the valve within the lantern.

g is a conical valve-seat formed around the aperture 9, adapted toreceive and fit tightly the pointed or'conical end of the valve-screw F,which forms the valve; Those constructions in which the oil-conductingdevices and the regulating-valve or stop-cock are situated upon theoutside of the lantern have been found very objectionable from theinterference caused by ice and snow in winter, and have been faulty,moreover, from the fact that the supply-pipe cannot be supportedsecurely. Upon the other hand, those constructions in which both thevalve and the valve-screw were located entirely on the inside of thelantern have been found objectionable from the factthat on manipulatingthem the lamp-door must be frequently openedand closed several timesbefore the burner is in proper working Application filed April 15, 1852.(N0 model.)

| order, and from the fact that the handle of the screw becomes very hotfrom the heat of the burner.

One object of this invention is to make a conduit for a street-lampburner in such shape that it shall have no corners, angles, recesses, orpockets which canserve as receptacles to catch and stopimpurities thatmay be in the oil, but shall allow all impurities, especially water, topass directly from the reservoir through to the burner. Heretoforeconduits for street-lamps have been made with receptacles (generallycalled traps to arrest and catch the water that may have found access tothe reservoir or other part of the attachment less rocking or motioncaused by the wind or otherwise, and the water pockets or traps, whenthe lamps are thus moved, often throw back into the oil conduit thewater which on to theburner and immediately extinguishes the light. Thissame result is caused often by a rapid flow of oil from a new reservoir,or a newly-filled one, the oil running into it some of the waterpreviously collected therein.

Another object'of the invention is to provide a street-lamp with aconduit made of tubing which shall have no bends or curves in 80 thepiece or pieces of tubing, but which shall have, however, two or moreparts inclined to each other, one part extending downwardly from thereservoir and the other attached to the burner, the two parts of thetubing 85 being detachably connected as nearas possible at the lower endof the down pipe. The pieces of tubing of which these conduits are mademust be frequently cleaned, and when they are bent or curved, as they 0have been heretofore, the cleaning is much' more dii'iicult than whenthey are made perfectly straight.

It will be seen that with my construction any liquid passing from thereservoir will 5 flow continuously through the conduit and directly tothe burner. Therefore in case water gets into any part oftheattachment-s it will but these street-lamps are subject to more or 65' they have collected, and this water passes the water pocket or trap,and carrying out of pass immediately down to the burner, and not beintercepted during its flow through the pipes.

Many advantages are incident to a construction of this nature. YVhen thelamp-lighter undertakes to light a lamp having a conduit of thischaracter, he perceives at once whether there is any water in theburner, the oil, or the attachment, because the water, being unimpeded,will immediately come to the burner and prevent his lighting it but inthose constructions having receptacles or traps for the water there willnot necessarily be a prevention of ignition, as the water willbetemporarily stopped, and therefore the lighter may be deceived, andafter leaving the lamp the water will be thrown into the-conduit againin some of the ways and with the results above set forth. Should alighter using a lamp of my construction find that there is water in theburner he can immediately detach the atomizer, tubing, and the burnerand replace them with others which are dry. Before doing this he cutsoff the supply of oil by the valve F. Therefore it is very important, inorder to obtain the best results with lamps of this char acter, that theconduits should be formed without anybends or crevices or receptacles,so that there shall be provided for the liquid a substantially unbrokenpassage to prevent the stopping of water or other impurities, and alsothat the regulating devices should be arranged to project through thewall of the lamp, so as to be readily controlled for cutting off thesupply both when there is danger of accident and when it is necessary todetach a wet burner.

I am aware that streetlamps have been here tofore constructed with fouror more pieces of tubing or pipes on the inside of the lantern, two ormore of the pipes lying in different planes for conducting downward, andtwo or more also lying in different planes for conducting horizontallyor inward and I do not claim, broadly, such devices as my invention.Such construction is shown, for instance, in an English patent toHearson, No. 1,769, of 1877; but the devices constructed after thismanner are not capable of the convenient manipulatio'n of which mine is;nor are they constructed as simply, or so as to accomplish the samepurposes. In those referred to the horizontal pipe connected directly tothe burner has not been utilized as a retort or atomizer, the retortportion of the conduit being considerably above the burner, andtherefore there is necessity of several intervening parts,

which I'avoid. Moreover, these devices do not allow of a cutting off ofthe supply of oil in case of a large flame inside, unless the hand ofthe operator be thrust inward through the lantern to the cut-off valvesituated at a suitable distance above the burner. \Vhen the parts areconstructed and arranged as I have shown and described, the flow of oilcan be immediately stopped from the outside, and

the retort, and the burner connected directly to the retort, can bedetached if it is necessary to supply a dry retort. To remove the retortfrom the devices used heretofore has necessitated the taking out of alarge part of the attachment, which is a matter of great inconvenienceand difficulty, whereas in my case it can be done by simply turning theburner round two or three times to disengage the connection of theretort with the down pipe.

\Vhat I claim is- I 1. In a street-lantern attachment, the combinationof the unbent down pipe D, the burner 0, provided with a threadedsocket, c, the unbent packed removable retort-pipe I, screwthreaded atboth ends and lying from end to end substantially at right angles to theburner, the elbow E, having the screw-threaded socket e, engaging withthe down pipe D, the screwthreaded socket c projecting through the wallof the lantern in the horizontal plane of the burner, the screw-threadedsocket c, engaging with the end of the unbent pipe I, whereby the burnercan be held in the proper position, and in connection with the packedretort-pipe I, can be disconnected from the lantern by rotating it on anaxis substantially at right an- I gles to the burner, and the valvescrewF F passing through the wall of the lantern, wherebythe flow of oil canbe shut off and the flame stopped without the necessity of inserting thehand into the lantern, said elbow E and the unbent pipes beingconstructed and arranged, substantially as set forth, to not havepockets or traps for the gathering of wa ter.

2. I11 astreet-lantern attachment, the combination of the unbent downpipe D, the burner G, the unbent packed retort-pipe I, situated at rightangles substantially to the burner, the elbow E, having the socket e toengage with the down pipe D, the socket e at an obtuse angle to thesocket c, to allow the retort-pipeI and burner O to be held in properposition, and the threaded socket c situated in the horizontal plane ofthe burner, and projecting outwardly through the wall of the lantern,and the valve-screw F F, having its head outside of the lantern, all ofsaid parts being arranged substantially as set forth, to prevent thecollection of water, and to perinit the cutting off of the oil andstopping of the flame from the outside, in order that the retort-pipe I,in connection with the burner, may be unscrewed by rotating them on theaxis of the valve-screw F F, substantially as set forth.

3. In a street-lantern attachment, the combination of the unbent downpipe D, the burner O, the unbent packed detachable retort-pipe I, theelbow having the socketve, which engages with the unbent retort-pipe I,and having the socket 6*, which projects through the wall of thelantern, and has the internally-threaded part, c", and the bottom screwF F, passing from the outside to the I 286.763 I l 3 In testimonywhereof I affix my signatui e in wall, 6', situated on or nearly on thehorizonpresence,0f two witnesses.
